Abstract (en)
[origin: EP3648181A1] A semiconductor light emitting device 10 includes a light extraction layer having a light extraction surface 22b. Multiple cone-shaped parts 52 formed in an array is provided on the light extraction surface 22b of the semiconductor light emitting device 10. A proportion of an area occupied by the multiple cone-shaped parts 52 per a unit area of the light extraction surface 22b is not less than 65% and not more than 95% in a plan view of the light extraction surface 22b, and an aspect ratio h/p defined as a proportion of a height h of the cone-shaped part 52 relative to a distance p between apexes of adjacent cone-shaped parts 52 is not less than 0.3 and not more than 1.0.
